Small breeding tray converted into a cage by soldering 

 wires to the sides and enclosing it in a mosquito net. 

 Such a cage is suitable for keeping Tabanidae in order 

 to get them to lay eggs. 



Large tray for rearing tabanid larvae (see page 303). 

 A large tray similar to the above converted into a cage 

 for keeping large numbers of flies such as Musca, 

 Sarcophaga, or Lucilia. 



A smaller cage suitable for breeding Musca, etc. 

 The mud enclosure (see page 314) on the left; three 

 glass jars fitted up for breeding experiments with 

 Musca (see page 344) ; the one on the left shows the 

 method of fixing the tin frame, the one on the right 

 shows the food receptacle suspended in the cage. The 

 two smaller jam jars with screw tops each contain a 

 tabanid larva; these jars may be used for a variety of 

 experiments. The above Photographs were taken by 

 Dr. Gibson.
